Using the previously reported vibrational results (infrared, Raman and resonance Raman spectra) for the Ce 2 O 2 S and solid compounds (see Part I), comparative lattice dynamics calculations were performed. These Ce 2.0 O 2.5 S calculations allow one to reproduce satisfactorily the experimental wave
